Degg's model

Question 1

what does deggs model say

Answer 1

A disaster will only occur when a ​vulnerable population (one that will be significantly disrupted and damaged) is exposed to a hazard.

Degg’s model is a good representation of this concept. If the population is not vulnerable, the hazard will not have a significant effect, thus the event will not be ​disastrous​.

Question 2

This shows the intersection between a hazardous natural event, such as an earthquake, hurricane or landslide and a vulnerable population which experiences human and/or economic loss, to create a ……..

Answer 2

disaster

Question 3

A threshold level is often used to determine whether the impact of an event is large enough to be considered a disaster, such as:

Answer 3

10 or more deaths

100 or more people affected

US $1 million in economic losses

Question 4

The relationship between risks, hazards and people is complex, due to:

Answer 4

unpredictability of hazard’s timing and magnitude, catching people out

lack of alternatives - people staying due to a lack of options (work, lack of space, skills or knowledge)

dynamic hazards - threats change over time and can be affected by human influence
cost-benefit (OCR GCSE science, anyone?)

‘Russian roulette reaction’ - fatalism, acceptance of risks whatever you do
